Habits and Persistent Food Restriction in Patients with Anorexia Nervosa: A Scoping Review.

The aetiology of anorexia nervosa (AN) presents a puzzle for researchers. Recent research has sought to understand the behavioural and neural mechanisms of these patients' persistent choice of calorie restriction. This scoping review aims to map the literature on the contribution of habit-based learning to food restriction in AN.

Handgrip strength is associated with 12-month survival in male patients suffering with advanced chronic liver disease.

Background: Advanced chronic liver disease (ACLD) patients are usually malnourished, and both conditions in combination increase the likelihood of unfavourable clinical outcomes. Handgrip strength (HGS) has been suggested as a relevant parameter for nutritional assessment and predictor of adverse clinical outcomes in ACLD. However, the HGS cut-off values for ACLD patients have not yet been reliably established.

Degree of food processing and association with overweight and abdominal obesity in adolescents.

Objective: To evaluate the association between the degree of food processing, overweight, and abdominal obesity in adolescents.

Methods: This is a cross-sectional study, with 576 adolescents aged 10 to 17 years, of both sexes. Food consumption was collected using the Food Frequency Questionnaire and foods classified as in natura or minimally processed, processed foods associated with culinary ingredients, and ultraprocessed foods.

Specific nutrition evaluation of patients with advanced chronic liver disease: Development and validation.

Background: Malnutrition is frequently identified in patients with advanced chronic liver disease (ACLD), and its early identification is necessary for effective nutrition treatment. The aim of this study was to develop and validate a tool for specific nutrition evaluation of patients with ACLD (SNE-ACLD).

Methods: SNE-ACLD was developed by consensus among experts using Delphi technique.

Metabolic and nutritional triggers associated with increased risk of liver complications in SARS-CoV-2.

Obesity, diabetes, cardiovascular and respiratory diseases, cancer and smoking are risk factors for negative outcomes in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which can quickly induce severe respiratory failure in 5% of cases. Coronavirus disease-associated liver injury may occur during progression of SARS-CoV-2 in patients with or without pre-existing liver disease, and damage to the liver parenchyma can be caused by infection of hepatocytes. Cirrhosis patients may be particularly vulnerable to SARS-CoV-2 if suffering with cirrhosis-associated immune dysfunction.

Influence of sugar consumption from foods with different degrees of processing on anthropometric indicators of children and adolescents after 18 months of follow-up.

Excessive consumption of ultra-processed foods is associated with the development of metabolic changes in children and adolescents. However, the consumption of total sugars, monosaccharides and disaccharides present in these ultra-processed foods and other food groups and its association with anthropometric indicators must be evaluated. Therefore, this study aimed at analysing the influence of sugar consumption from foods with different degrees of processing on anthropometric indicators of children and adolescents after 18 months of follow-up.

Restrained eating behaviour, anorexia nervosa and food consumption between children and adolescents: a scoping review.

Anorexia nervosa (AN) and restrained eating behaviour (REB) are characterised by reduced food intake to achieve body weight loss. This scope review aimed to describe the existing evidence on the association between AN, restrictive eating behaviour and food consumption. Studies with children and adolescents of both sexes of all races and ethnicities were included.

Influence of nutritional assistance on mortality by COVID-19 in critically ill patients.

Background & Aims: Evidence suggests the existence of an association between the institution of nutritional therapy and clinical outcomes in patients with critical COVID-19. Thus, the aim of this study was to evaluate the influence of nutritional assistance on COVID-19 mortality in patients admitted to intensive care units (ICU).

Methods: This is a subset of the cohort "Influence of nutritional therapy on clinical prognosis in patients with COVID-19: a multicenter retrospective cohort study".

Body Adiposity and Apolipoproteins in Children and Adolescents: A Meta-Analysis of Prospective Studies.

Background: Excess Weight and Cardiovascular Diseases are health problems with increasing prevalence among children and adolescents, hence the need to investigate the issues related to them to better deal with the problem.

Objective: To investigate the influence of excess adiposity on the levels of apolipoprotein B and A1 in children and adolescents.

Methods: A systematic search was conducted in the PubMed, Embase, Lilacs, Web of Science, Ovid and Science direct databases, searching for cohort eligible studies and evaluating their results, methodological quality and risk of bias; combinable studies with good quality and low risk of bias were evaluated by meta-analysis.

Dietary patterns and cardiometabolic risk factors among adolescents: systematic review and meta-analysis.

Relevant scientific articles were searched in PUBMED, EMBASE, SCIENCE DIRECT, LILACS, WEB OF SCIENCE and SCOPUS. Observational studies that included the measurement of any CMR factor in healthy adolescents and dietary patterns were included.

Hypertriglyceridemic Waist Phenotype and Changes in the Fasting Glycemia and Blood Pressure in Children and Adolescents Over One-Year Follow-Up Period.

Background:: The hypertriglyceridemic waist (HTW) phenotype is defined as the simultaneous presence of increased waist circumference (WC) and serum triglycerides (TG) levels and it has been associated with cardiometabolic risk in children and adolescents.

Objective:: The objective was to evaluate the influence of HTW phenotype in the fasting glycemia and blood pressure in children and adolescents over one-year follow-up period.

Methods:: It is a cohort study involving 492 children and adolescents from 7 to 15 years old, both genders, who were submitted to anthropometric, biochemical and clinical evaluation at the baseline, and also after 6 and 12 months of follow-up.

Nutritional assessment in surgical oncology patients: a comparative analysis between methods.

Background And Aims: The malnutrition found in oncology patients is the main responsible for the increase in morbimortality and worsening of their quality of life. Currently, the assessment of malnutrition is performed by subjective and objective methods, or the combination of them. Although these methods are routinely applied and their association is very common in clinical practice, there are few studies on the agreement between them.
